TIF and TWF files

Some FileName1.tif files have an associated FileName1.twf file that gives the geographic co-ordiate when used together. Is there a way to load the *.twf file when viewing the *.tif file so the x:###,y:### cord displayed at the bottom of the screen has a real meaning in geo terms?

Sorry, hit the submit then saw the 'upload attachment' tab

The top left corner (pixel) of the image has a world co-orinate of   -49943.826157 and -3758301.280434

The file was exported at a resolution of 0,5m in the x and 0,5m in the y direction per pixel, thus the bottom left co-ord should end up around  -50065.826 and -3758392.280

I have no idea what the two lines of 0 are.

Regards,
Ian
